I'm ordering some new RHP from ProProducts and wanted to share the update I just got from Bob, as this will affect anyone ordering heat panels or new enclosures.
Be patient with the folks you are ordering from -- they have no control over this.
That said, I am certainly not going to complain about a 4 week (or longer) turnaround time under the circumstances.
"I just want to make sure you are aware that material shortages have become much worse due to the Ukrainian conflict (Russia is one of the largest producers of aluminum in the world) and it will probably take about 4 weeks to make this panel."
